Given varying weather conditions, I have had many different "hay" combinations over the years. This year I had to get it from a different area, and the horses are doing very well on it. It was a newly seeded alfalfa field. It has a fair amount of alfalfa and oat cover crop, there is a fair amount of barnyard grass. The horses eat it all and was wondering if anyone has had experience with it . With alfalfa, I like roughage/fiber, so if it does that it would be OK.
